I have a number of these guys living in my apartment:
I'd guess there are at least a dozen of those suckers inhabiting my space. It's quite common to see them crawling up the wall or across my desk. I never kill or remove them. Usually when I see one darting across the wall it's after a silverfish or a mosquito and that's fine with me.
Spiders serve a purpose (eating bugs and feeding cats). I don't buy that spiders crawl into peoples mouths during sleep. Spiders are scared to death of anything bigger than them that moves, there's no way they want to crawl into a giants noisy blow hole at night, c'mon.
